Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for men aged 18 or older with prostate cancer that has not spread outside the prostate and was diagnosed within the last 9 months.
- Age
- 18 years or older
- Sex
- Men only
- Disease stage
- Prostate cancer confined to the prostate, diagnosed within the last 9 months. Gleason Score 7 (3+4 or 4+3). PSA 15 ng/mL or lower. Lesion volume on mpMRI under 1.5 cm3. Treatment target volume under 50 cm3. Cancer must not have spread to lymph nodes or elsewhere.
- Earlier treatment
- People cannot have had prostate surgery, pelvic radiation, TURP, cryosurgery of the prostate, brachytherapy, androgen deprivation therapy or chemotherapy for prostate cancer. No alpha-reductase inhibitors within 90 days of enrolment. People on active surveillance can join if the disease has progressed.
Main reasons for not taking part
- Cancer that has spread beyond the prostate or to lymph nodes
- Porphyria, allergy to verteporfin or porphyrins, or ongoing treatment with a light-sensitising drug
- Another treatment trial within the last 3 months
- Reasons that rule out MRI with gadolinium contrast, such as implants or severe kidney problems
- Bleeding disorder, now or in the past

Show all 31 criteriaShow less
Who can take part
- Subjects ≥ 18 years
- Sufficient bone marrow reserve as indicated by; granulocyte count ≥ 1500/mm3, platelet count ≥ 100,000/mm3
- Adequate renal function as defined by creatinine ≤ 1.5 mg /dl
- Adequate hepatic function, based on a total bilirubin ≤ 1.5 mg/dl, serum glutamate-oxaloacetate transaminase (SGOT) ≤ 3 times the upper limit of normal, and alanine transaminase (ALT) ≤ 3 times the upper limit of normal
- Only persons who use an effective method of contraception (condom is recommended) or whose sexual partner is de facto unable to conceive a child for other reasons are included
- Signed Informed Consent
- Histologically confirmed organ-confined prostate cancer diagnosed within the last 9 months. Including subjects on active surveillance with evidence of disease progression and a prostate biopsy not older than 9 months. a. This prostate biopsy should be targeted and systematic (transperineal or transrectal are both acceptable) and include both systematic sampling with a minimum of 8 cores (4 right, 4 left) as well as MRI fusion targeted cores. The minimum number of targeted cores is two (2) but more may be included at the discretion of the surgeon
- Gleason Score 7 (3+4 or 4+3)
- PSA ≤ 15 ng/mL
- Lesion volume on mpMRI < 1.5 cm3
- Adequate stage imaging such as pelvic CT/MRI/PET scan within the last 6 months confirming localized cancer. • Bone scan is optional if PSA < 10 ng/mL
- Treatment target volume <50 cm3 defined by TRUS or MRI
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- Expected survival ≥ 36 months
Who cannot take part
- Use of Alpha-reductase inhibitors (ARIs) within 90 days of enrolment
- On-going therapy with a photosensitizing agent
- Enrolment in another therapeutic clinical study within 3 month prior to enrolment and throughout the study
- Prior radical surgery for carcinoma of the prostate, prior pelvic radiation, prior TURP, prior cryosurgery of the prostate
- Prior treatment with any form of brachytherapy
- Previous androgen deprivation therapy (ADT) or chemotherapy for prostate cancer
- Prior or current bleeding diathesis
- Evidence of locally advanced, regional pelvic lymph node metastasis, or metastatic disease
- Mental incapacity or psychiatric illness that would interfere with the subject’s ability to understand and give informed consent or to complete follow-up visits according to the judgement of the investigator
- Contraindication for photosensitizer including: a. Porphyria or other diseases exacerbated by light. b. Known hypersensitivity to verteporfin for injection (VFI) or to any of the excipients. c. Known allergies to porphyrins
- Has known hypersensitivity to pancuronium bromide, atricurium or cisatricurium
- High volume GG1 disease in the contralateral prostate, outside of the ablation zone. High volume is defined as >1 core of GG1 with a linear amount of carcinoma >6mm
- Any serious active or co-morbid medical conditions, laboratory abnormality, psychiatric illness, active or uncontrolled infections, or serious illnesses or medical conditions that would prevent the patient from participating or to be managed according to the protocol (according to investigator's decision)
- Contraindication for MRI/Gadolinium contrast such as: implants, hip prosthesis, severe renal impairment (glomerular filtration rate [GFR] <30 mL/min/1.73m2), or previous contrast reactions
- Any suspicious for, probable, or definite extracapsular extension on pretreatment MRI
- Contralateral PIRADS 4/5 lesion (even if negative targeted biopsy)
- Tumors known to be eroding into a major blood vessel in or adjacent to the illumination site

About the trial
What the trial wants to find out
To demonstrate that the use of the SpectraCure P18 System and verteporfin for injection is a safe treatment for patients with organ-confined prostate cancer diagnosed within the last 9 months Patients will be subject to a dose escalation to determine the safe maximum light threshold dose starting at 20 J/cm2.
